Description

Device and method having both scanner function and mouse function at the same time {APPARATUS AND METHOD FOR IMPLEMENTING MOUSE FUNCTION AND SCANNER FUNCTION ALTERNATIVELY}

The present invention relates to a device and a method for simultaneously implementing a scanner and a mouse function, and specifically, to detect the X, Y axis position movement of the device according to the present invention using a portion of the input device of the scanner, the detection Sends the X and Y axis movement information to the computer so that the device can be operated with a mouse, and transfers the detected image along with the X and Y axis movement information of the device to a computer or other device so that the device can The present invention relates to an apparatus and a method for simultaneously implementing a scanner and a mouse function to enable a computer to operate.

Scanners generally use CCDs (Charge-Coupled Devices) or CIS (Contact Image Sensors) to sequentially read the various images printed on the ground and store the images in line units in the storage device. Acquire an image of one page. The obtained image is transferred to a computer via a cable and output on a screen or a printer.

In order to obtain an accurate image, it is important for the scanner to move the CCD and the CIS at a constant speed and to detect light reflected from the ground, thereby accurately detecting the voltage generated by the CCD and the CIS.

The scanners of the present invention have various sizes, but the structures that can move constantly because it is important to move the CCD or CIS, which is a component of the scanner, with respect to the document or move the document with respect to the CCD or CIS. Is installed. Such constant moving structures include the movement of rollers or fixed posts.

The mouse can be divided into a ball mouse and an optical mouse. In the case of a ball mouse, the device detects a user's movement by converting a mechanical movement into an electrical signal, and sends a relative change amount in the X and Y axes to a computer so that the user can place the pointer at a desired position. On the other hand, the optical mouse detects the amount of light reflected from the ground, and based on this, detects the movement of spots (defects or paper grains) on the ground and sends the relative amounts of movement to the X and Y axes to the computer. It is a device that allows the user to place the pointer in the desired position.

Conventional scanners and optical mice have the same properties in that they detect images on the ground, but scanners require structures that move the scanner's detectors, CCD and CIS, in a straight line at a constant speed.

Although it is possible to physically make the scanner and the mouse into one device, there is a problem that the size of the device is very large and inconvenient to use when the structure of each device is used as it is.

The present invention is to solve the above problems, by using a portion of the input device of the scanner can be used as a mouse, and also to deliver the detected image to a computer or other device that corrects or compensates for the shake of the image The present invention provides a device having a scanner function and a mouse function at the same time.

Another object of the present invention is to implement a mouse function and a scanner function simultaneously by using an input device having a scannable area including a location tracking area, thereby reducing the size of the device compared to the case of using a mouse and a scanner, respectively. In addition, it reduces the number of connectors in the computer and reduces the area of the scanner compared to the general scanner, and makes it easy to perform scanning when there is a document or an image that needs scanning while using the mouse function. It is to provide a device for improving.

1 is a block diagram of a device having a scanner function and a mouse function simultaneously according to the present invention, Figure 2 is a block diagram of the input device of FIG. In FIG. 2, the location tracking areas 220 and 230 are set at two ends of the scanable area of the input device 100 for accurate position movement detection. However, the location tracking area may be set to only one location and various modifications may be made. It is possible.

As shown in FIG. 1, the apparatus 10 is largely composed of two parts, that is, the input apparatus 100 and the image processor 110. As shown in FIG. 2, the input device 100 is implemented as an image input device such as a CCD or a CIS that detects light reflected from the light source to the ground and changes the voltage. In addition, the input device 100 includes position tracking areas 220 and 230 and an actual scan area 210 for position movement detection of the device 10. In this way, the signal generated by the input device 100 is provided to the image processor 110.

The image processor 110 includes an analog / digital (A / D) converter 112, a controller 114, a memory 116, and a select button 118.

The analog-to-digital (A / D) converter 112 receives a signal input from the input device 100, converts the received signal into a digital signal, and provides the same to the control device 114. The selection button 118 receives a selection of a function to be used among the mouse function and the scanner function from the user and sends it to the control device 114.

The control unit 114 stores the digital signal received from the A / D converter 112 in the storage unit 114, and when a certain amount of image information is collected in the storage unit, the location tracking areas 220 and 230 shown in FIG. ), The X and Y axis position shift of the apparatus 10 is detected. In addition, the user inputs the signal input from the selection button 118 to determine the user's selection, and the user moves the detected X, Y axis position of the apparatus 10 and the image data detected from the actual scan area 210. Transfer to computer 120 to suit the selected function. At this time, a separate transmission device may be installed between the control device 114 and the external computer 120, and such a transmission device may use a USB port.

When the user selects the mouse function through the selection button 118, only the information of the X and Y axis movement of the apparatus 10 is transmitted to the computer 120, and when the user selects the scanner function, it is shown in FIG. The X and Y axis position movement information of the apparatus 10 detected from the image input from the actual scan area 210 and the image read from the location tracking areas 220 and 230 are transmitted to the computer 120 together.

In this case, the computer 120 is provided with software for moving the pointer of the computer 120 by using the information of the X, Y axis position movement of the apparatus 10 received from the image processor 110, and the apparatus ( 10) is a device that can compensate the input image data using the X, Y axis position shift information.

In addition, since the apparatus 10 is a device having a scanner function and a mouse function at the same time, one of the scanner function and the mouse function is selected and different operations are performed according to the selection.

Hereinafter, a process of selectively operating a scanner function and a mouse function according to the present invention will be described with reference to FIGS. 3 to 5.

3 is a flowchart illustrating a process of selectively operating a scanner function and a mouse function according to the present invention, FIG. 4 is a flowchart illustrating a process of detecting X, Y axis position movement of the apparatus according to the present invention, and FIG. It is a figure which shows the method of detecting X, Y-axis position shift from the memory | storage device of the apparatus which concerns on this invention.

First, a selection of one of a scanner function and a mouse function is received from a user (S310). Thereafter, the X and Y axis position movements of the apparatus 10 are detected (S320) and it is determined whether the X and Y axis position movements have occurred (S330). The X, Y axis position movement detection operation of the present apparatus 10 is shown in Fig. 4 and will be described later.

When the apparatus 10 does not move in the X and Y axes, the user receives input of a selection of either the scanner function or the mouse function, and detects the X and Y axis movement of the apparatus 10.

When the apparatus 10 moves the X and Y axes, it determines the function received from the user (S340). If the function input from the user is a mouse function, only the information on the X and Y axis movement of the device 10 is transmitted to the computer (S350). If the function input from the user is a scanner function, the function of the device 10 is transmitted. The image data scanned in the actual scan area 210 is transmitted to the computer 120 together with the information on the X and Y axis movement (S360).

Through the above operations, the apparatus 10 can be used simultaneously with the scanner and the mouse, and it is possible to easily scan the necessary documents or images during use with the mouse.

As described above, in order to enable the present apparatus 10, it is essential to detect the X and Y axis movements of the present apparatus 10. Hereinafter, the X, Y and the present apparatus 10 will be described with reference to FIG. The operation of detecting the Y-axis position shift will be described.

First, the input device 100 generates data for a predetermined line or surface (S410). The data generated by the input device is stored in the storage device 116 (S415). Thereafter, it is determined whether the position of the device 10 can be detected from the data stored in the storage device 116 (S420).

If the position of the device 10 cannot be detected from the data stored in the storage device 116, the step of repeatedly storing the data for a predetermined line or surface generated by the input device in the storage device is repeated. .

If the position of the apparatus 10 can be detected from the data stored in the storage device 116, as shown in Fig. 5, the constant area is read from the data stored in the storage device (S425), and this constant is determined. Obtain the image center or the image itself 510 on the ground in the area, or obtain and store the X, Y coordinates of the reference point through the spot generated on the ground (S430).

Thereafter, the input apparatus 100 again generates data for a predetermined line or surface (S435), and deletes data for the first predetermined line or surface among the data stored in the storage device 116 and first stores the remaining stored data. After moving in a predetermined line or plane direction, data is stored in the last predetermined line or plane (S440).

A predetermined area is read again from the data stored in the storage device 116 (S445), and the X, Y of the reference point is obtained through the spot generated on the ground or the image center on the ground or the image itself 520 in the predetermined area. Obtain the coordinates again (S450). Thereafter, the X and Y coordinates of the newly obtained reference point are compared with the X and Y coordinates of the previously obtained reference point to detect the X and Y axis position movement of the apparatus 10 (S455).

The X, Y axis position movement of the apparatus 10 can be obtained by the above method, and the X, Y axis position movement information of the apparatus 10 thus obtained is determined by the computer 120 by the user. It is used to compensate for an image that has been positioned or scanned in the actual scan area 210 of the input device 100.

At this time, when the device 10 is used together with a pad marked with a grid, the grid displayed on the pad may be used as a reference point to obtain the X and Y axis movement of the device 10. It is possible to improve the operation accuracy of the mouse function or the scanning function of the device 10.

By setting two position tracking areas 220 and 230 in the input device 100, the amount of rotation of the device 10 can also be measured by moving the X and Y axes of the device 10. The method of measuring the rotation amount of the apparatus 10 will be described with reference to Figs. 6A to 6D.

FIG. 6A shows the location tracking areas 610 and 620 set in the input device of the device 10, and FIG. 6B shows that the control device 114 is connected to the input device while the user uses the scanner function of the device 10. FIG. The images continuously read through the location tracking areas 610 and 620 are shown. 6C also detects the positional shift of each spot through the spots of the ground shown in the images read from both ends of the apparatus 10, and shows the positional shift of the spots of the detected respective sites as vectors. FIG. 6D illustrates the relative motion of the B part based on the A part in the straight motion and the rotational motion.

First, while the user uses the scanner function, images are sequentially read through the two location tracking areas 610 and 620 of the input device to detect the spots of the ground (630 and 640). The shift of the detected spots 630 and 640 is detected to represent the shift of the spot as a vector (650 and 660).

Subsequently, by subtracting the vector obtained above, the amount of the linear motion in the X direction or the Y direction of the other end based on one end of the position tracking areas 610 and 620 is obtained.

In this case, the linear motion in the X direction may be dX ₂ -dX ₁ , and the linear motion in the Y direction may be represented by dY ₂ -dY ₁ . By dividing the amount of the linear motion in the Y direction by the amount of the linear motion in the X direction, the amount of rotational motion of the device is obtained. The mathematical expression of the rotational motion of the device 10 is It may be represented by Equation 1.

tan Θ = (dY2-dY1) / (dX2-dX1)

The amount of rotational movement of the apparatus 10 obtained by the above operation can be used by the computer 120 to compensate for image data.

The image transmitted by the device 10 to the computer 120 can be compensated based on the X, Y axis position shift of the device 10, and this X, Y axis shift is now described with reference to FIG. The image compensation operation according to FIG.

7 is a flowchart illustrating an image compensation process for shifting a device according to the present invention.

First, at the time point at which image reception is started, the related variable is initialized (S710). After initialization, the X and Y axis positions of the apparatus 10 obtained through the position tracking region of the input apparatus 100 in predetermined line units are moved. Information and image data collected in the actual scan area of the input device 100 is received and stored (S720). Thereafter, the moving speed of the apparatus 10 in the X direction is calculated (S730). The speed V in the X direction can be expressed by the following equation.

V = ΔX / ΔN

Where ΔX is the travel distance in the X direction and ΔN is the number of lines received.

At this time, when the user moves the apparatus 10 slowly, the number of lines received increases, and when the user moves the apparatus 10 quickly, the number of lines received for the same X-direction moving distance becomes small.

Thus, in order to compensate for the number of different lines according to the moving speed of the apparatus 10, the line is compensated in correspondence with the moving speed of the apparatus 10 (S740). At this time, if the moving speed of the device moved by the user is slow, the compression compensation of the line, if fast, expansion compensation. The apparatus 10 is configured to have a speed of reading an image fast enough to calculate a moving speed even for a fast movement of a user.

Thereafter, the image modified in the X direction as described above is compensated for the Y direction again (S750). Correction in the Y direction is for vibrations that may occur when the user moves the apparatus 10, and the image data may be simply shifted by the position shift in the Y direction. Finally, as described above, the compensated image data in the X and Y axis directions are stored (S760).

Thereafter, it is determined whether scanning is finished (S770). If the scanning is not finished, the above-described process is repeated until the scanning is completed. If scanning is completed, the image compensation operation ends.

If necessary, the compensated image information may be output through an output device such as a monitor or a printer, or may be used for an OCR (Optical Character Reader).

The present invention provides a scanner function and a mouse function at the same time by using a portion of the input device of the scanner to be used as a mouse and to transfer the detected image to a computer or other device for compensating for use as a scanner. .

In addition, the present invention reduces the size of the device by implementing a mouse function and a scanner function at the same time by using an input device having a scannable area including a location tracking area, and if the scanning operation is required while using the mouse function, the scanning operation is easily performed. Can be done.

As described above, since the scanner and the mouse are configured as a single device, the device according to the present invention uses a different device to use an image or text when there is a necessary part in a book, a business card, or a notebook while using the mouse. Instead of using a mouse and a scanner, scanning can be easily performed using the same device, thereby reducing the size of the device and improving work efficiency and efficiency.
